APPARATUS FOR THE MANUFACTURE OF GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 431,874, dated July 8,1890.

Application filed March 24:, 1890- Serial No. 345,098- (No model.)

To all whom it may concern.-

Be it known that I, WILLIAn BUTTLER, of Fostoria, in the county ofSeneca and State of Ohio, have invented a new and useful Improvement inApparatus for the Manufacture of Glassware, of which the following is afull, clear, and exact description.

My invention relates to the construction of apparatus for reheating,fire-polishing,and finishing articles of glassware where the usualglory-hole cannot be conveniently or economically employed.

Ileretofore the common method of fire-polishing and final forming ofglassware'has con:

sisted in removing the article from the mold,-

reheating it in a glory-hole, and finally shaping it by hand or ahand-tool. This involves loss of time and labor, and is not productiveof uniform results. To avoid this, apparatus has been devised whereinwas combined'with a fixed platform for the reception of molds swinginggas and air jets adapted to be swung over and away from the mold, so asto apply heat to the article contained in the mold; but owing to thefact that said devices did not embody means for storing the heat anddeflecting it, or reflecting and radiating it, they have been butpartially efficient in their action, and, owing to the fixity of theircharacter, they involved loss of time and labor in handling the moldsand adjusting the apparatus.

The object of the present invention is to simplify and render effectiveand portable the devices for reheating and finishing articles ofglassware, as well as to remove such restrictive features as rendertheir applicatiorl limited. To this end the main feature of theinvention embraces a portable heating device wherein is combined with agas-j et or equivaof the hood or heat-storer, all as will herein aftermore fully appear.

I will now proceed to describe the preferred form of my apparatus sothat others skilled in the art may apply the invention.

In the drawings, Figure 1 is a plan view of a glassmold, showing myimproved apparatus applied thereto. Fig. 2 is a vertical sectional viewon the line II II of Fig. 1. Fig. 3 is a similar sectional view showingthe finishing-tool. Fig. 4: is a vertical section of a modified form ofmy improvement.

Like symbols of reference indicate like parts in each.

The mold illustrated has a cavity adapted to shape a glass bottle; butit will be understood that while my invention is peculiarly fitted forthe finishing of bottle-necks it is not limited thereto, but is capableof general application, as above stated. The mold has a bottom plate 2,separable portions 3, forming the cavity in which the body of thearticle is blown, and a separable ring portion. 1 at the top.

Figs. 1 and 2 illustrate the preferable construction of my improvedportable heating or glory-hole device. It consists of an invertedrefractory (preferably fire-clay) cup 4, having openings 5 and 13 at theends, and having a lateral opening 7. It is preferably provided withsmallfeet' 6, which afford at the bottom a space for the entrance of airinto the interior of the cup. The opening 5 is for the escape of theproducts of combustion, as hereinafter stated, and may be locatedotherwise than as shown in the drawings.

8 is a jet-pipe, which is secured to a ringer frame 9, adapted toencircle the cup 4 and to be held thereto by set-screws 10 or otherwise.The nose of the pipe 8 is connected with a flexible supply-pipe 11, andis directed toward the hole.7, and is preferably a little remotetherefrom. \Vhen gasis discharged from the nose of the pipe 8, it willenter the hole 7 in the cup, inducing with it a supply of air, and whenignited will burn in the interior of the cup, producing therein heatsufficient to raise the refractory substance of the latter to a hightemperature.

I shall now describe the manner in which the heating apparatus justdescribed may be used for the purpose of finishing a glass article whilein the mold. The glass article isblown in the m old in the usual manner,and when the blow-pipe is pulled off,so as to remove theblowover,themold parts 1 are opened, so as to expose the neck. Then to reheat theneck preliminary to shapingitthe cuptis placed on the mold parts 3 overthe projecting neck of the glass article, which is Very rapidly heatedthereby to the required temperature for finishing and shaping. Anincidental effect of the gas jet is also to melt all loose and fineparticles of glass, forming the remnant of the blow-over, and to causethem to be incorporated in the bottle-necks. NVhen the neck has beenheated, the cup is removed, and while the article is still in the mold arevolving shaping-tool 12 is brought down upon it, so as to finish theneck to the desired shape. The mold may then be opened and the glassarticle removed and put into the lear. This method of finishing thearticle while it is in the mold is of very great utility in saving thelabor usually expended in handling the glassware during its removal fromthe mold, its reheating at the furnace, and its subsequent shaping. Idesire it to be understood that said device may be employed for thepurpose of heating glass articles after their removal from the mold. Itseasy movability, its simplicity, and the small amount of fuel requiredin its use render it of very great utility, and its employment resultsin a material saving of labor and time in the manufacture of glassware.

The apparatus may be modified in many Ways, since considered, broadly,the essentialfeatu re of its'construction consists in a movable devicecomprising a gas-jet and a refractory block or surface on which thegas-jet impinges, and which is heated thereby, so as to radiate suchheat to the glass article opposite to which it may be placed. Theform ofconstruction shown in Figs. 1 and 2, however, possesses certain markedfeatures of advantage in the rapidity with which the heating operationcan be performed, and I desire to claim such construction hereinspecifically.

In Fig. 4 I show a modification of the heating device, in which the cupis replaced by a simple refractory block, which is heated by the flameof one or more gas-jets, and which on being placed over the glassarticle will communicate its heat thereto. Other modifications of thedevice will suggest themselves.

The advantages of my invention will be appreciated by those skilled inthe art. It affords a distinct saving in the cost of manufacture byreducing the number of hands necessary to be employed in finishing thearticle,

it enables the employment of less skilled labor, and makes the work muchless arduous. In addition to these merits, when the articles are shapedin the mold the product is uniform, and the shape cannot be distorted aswhen the articles are removed from the mold and reheated at a glory-holefurnace before shaping.

I claim 1. A portable heating apparatus for glassware, consisting in thecombination of a refractory hood or heat-storing substance and agas-supply pipe, the flame from which impinges thereon, substantially asand for the purposes described. 7

2. A portable heating device for glassware, consisting in thecombination of a refractory cup having an opening for the glass articleto be heated, and a gas-pipe discharging into the cup, substantially asand for the purposes described.

3. A portable heating device for glassware, consisting in thecombination of a refractory cup having an opening for the glass articleto be heated, an escape-opening 5, and agaspipe discharging into thecup, substantially as and for the purposes described.

4. A portable heating device for glassware, consisting in thecombination of a refractory cup having an opening for the glass articleto be heated, supporting-feet, and a gas-pipe discharging into the cup,substantially as and for the purposes described.

5. A portable heating device for glassware, consisting in thecombination of a refractory cup having an opening for the glass articleto be heated, a gas-pipe discharging into the cup, and a frameconnecting the cup and gaspipe, substantially as and for the purposesdescribed.

6. A heating device for glassware, consisting in the combination of arefractory cup having an opening for the glass article to be heated, agas-opening, and a gas-pipe having its nose directed into saidgas-opening and situate outside the cup at a little distancetherefrom,substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 22d day of March,A. D. 1890.

IVILLIAM BUTTLER.
